While attempting to compile the Digi Etherlite 16/32 driver on aserver running Fedora Core 5 (2.6.17-1.2145_FC5-smp-i686), I ranacross this error:

/usr/src/redhat/BUILD/dgrp-1.9/driver/dgrp_net_ops.c:453: error:'struct tty_struct' has no member named 'flip'

The driver works in FC3 and FC4. Since I have the source for thedriver, my question is what has changed in the kernel and where do Ilook (in the kernel) to find what to change to make the drivercompatible with FC5?
